GlobalProtect VPN for iOS and Android Devices
Download the free GlobalProtect app from "Palo Alto Networks" (the 'Developer') from Google Play or the Apple App Store. You need to tell the app to connect to byod-vpn.nuff.ox.ac.uk (which may be termed the 'Portal'). Then use your usual Nuffield network login credentials to connect (usually firstname.lastname and password).
You should see a Microsoft log in, where you may possibly need to pick your Nuffield Microsoft account. The first time you use your Nuffield Microsoft account (usually using firstname.lastname@nuff.ox.ac.uk) you may be prompted to set up your MFA methods. See our page on Setting up Microsoft MFA for your nuff.ox.ac.uk account for full details.
